How different are you from your sibling/s?

Often times, I would think why is it that I have different views and thoughts from my other siblings. We sometimes argue because of things we can't resolve due to different rationale. We grew up together and yet we developed different reasoning. Don't get me wrong although we faced a lot of disagreement we still love each other.

my siblings are my bestfriends. i cook for them and they pamper me,too like giving my feet a massage.
we have different hobbies... like i am the one so into animals/pets. they are more into computer stuffs. but nevertheless, such a difference did not put too much gap between us.
however,i have this attitude to keep everything inside on my own. when i feel bad, i try not to let them know because i know they'll feel sad and i don't want them to feel sad, too. so, i cry on my own. i know it's better to share it to them, but i'd rather not. my brothers are always open to me. when they have problems, they tell me about it and they are always open to comments and suggestions.
